So you'd rather not win the lottery?
Because that's what utility-negative means. I doubt you mean that. What you mean is that the utility+ of potentially winning the lottery is less than the utility+ of the price of the ticket.
And that's fine. It's a complicated way of saying you don't want to play the lottery. And that's where I am too, to be clear.

I assume it is to you as well, or you would be playing it regularly.
No, because much like money, utility has degrees. Potentially winning a EV+ lottery is utility+. Having an extra dollar is utility+. It appears the latter is larger for you. That's fine - you don't need to bend over backwards to make "lottery is utility negative" arguments.
As a matter of fact, lots of people find even EV- lotteries U+. Not me and not you, but there's nothing stupid about what they do. The most U+ thing for me, investing in Callipygian Pharmaceuticals, is admittedly probably EV-.
EV and utility are somewhat independent. If you watch a movie, it's EV-/U+, and U(movie) > U(cost of movie). I could work on erectile dysfunction pills, and it'd probably be EV+, but U-. I'd take a lower EV+ to have a U+.
People love to smugly point out that the lottery is a stupid tax. But I think people who do that ignore the good things about the lottery, as well as many things that are lottery-like.
